NMWA (National Museum for Women in the Arts) in DC is opening for members and soon the public. They have new protocols in place for safety during the time of Covid19, and a new timed ticket system:
"NMWA Reopens for Members July 29
We have missed you! In appreciation of your steadfast support throughout our closure, we invite you to enjoy the museum before NMWA opens to the public on August 1. Join us for Member Appreciation Days, July 29–31. Revisit your favorite works in the collection, see Graciela Iturbide's Mexico before it closes August 23, and save 20% at the Museum Shop.
The well-being of our visitors, staff, and volunteers is our highest priority. In order to allow space for ample social distancing, we strongly encourage visitors to purchase timed tickets in advance. We have adapted our visitor experience for your safety and enjoyment while meeting new health guidelines and safety standards." (from their newsletter announcement).
This is a really fun museum to go to (and to go to with OR without kids) and has some gorgeous art. It also has an artists' book collection upstairs, which you may be able to ask to see (Ask them how). When I was student at the Corcoran, I go to see several of their books in that collection and it was a delight.
